To use the LAN-520X in a WAN environment, the following rules must be met:
•
Network Routers must be configured to connect the LAN subnets.
•
Ports 9999, 10001, and 10002 must be allowed to pass through the router.
•
The Gateway IP address must be configured for the LAN-520X Master and any LAN-520X slave
outside of the Master’s subnet. Use option 0 Server in the Telnet connection to configure the
Gateway.
•
No more than 12 IP addresses can be entered into the LAN-520X Master Hostlist.
NOTE: Configuration of Routers must be handled by knowledgeable IT personnel.

There are a few critical parameters to set via Telnet, all other parameters should be left at their default
values.
There are two ways to open Telnet, through the Lantronix DeviceInstaller window or by opening a
DOS box.
•
From the DeviceInstaller page, locate and double-click on the IP address of the LAN-520X.
Select the Telnet tab and then click on the
button.
•
Open a DOS box and open a Telnet connection to Port 9999 on the LAN-520X.
At the DOS prompt type the following to make the Port 9999 Telnet connection to the LAN-
520X:
- c:\>telnet <LAN-520 IP address> 9999 <Enter>
For example:
- c:\>telnet 192.168.100.250 9999 <Enter>
1. As soon as the Telnet sign-on screen appears, press <Enter> to go into the LAN-520X Setup
mode. There is a two to three second window in which you must press <Enter> before the Telnet
session automatically closes. If the Telnet session closes before you enter Setup mode (if nothing
happens when you press <Enter>), simply click the
box again to establish a connection to
Telnet.
2. Once Telnet connects with the LAN-520X all current configuration information is displayed and
the cursor is placed at the “Your choice” field (see Figure 4 on page 5).
